Lance Bass Will "Probably Cry" at Justin Timberlake"s Wedding

There might be more than one union worth celebrating come Justin Timberlake and Jessica Biel”s wedding day.

Although it”s been more than a decade since the boy band has been active, the occasion could be extra special for “N Sync, the “90s pop sensation that launched Timberlake”s career.

“It would be great. Who knows” former band mate and friend Lance Bass, 33, tells Entertainment Tonight Canada of the potential reunion. “You never know. We might do a little improv a capella [at the wedding].”

Wedding entertainment ideas aside, Bass says he has no details about the “hush-hush” wedding, rumored to be this summer. “I”m sure when the wedding comes about, no one is going to know until five seconds before,” he says.

Would that be enough time to plan a toast, if Timberlake calls on him for the couple”s big day

“I”ll probably cry,” says Bass, who helped the couple celebrate their engagement at a Los Angeles cocktail party last week. “That”s what I do at these things. If I have to do a speech, it”s something that means so much. The tears start coming.”
